Patent CA-2218934-A1 (CA)
Inventor: BELLER DIETER
IPC: H04N7/173
Filed: 1997-11-12
Abstract: METHODE UTILISEE DANS UN RESEAU DE TELECOMMUNICATIONS, UNITE DE TERMINAISON REALISANT CETTE METHODE ET RESEAU DE TELECOMMUNICATIONS COMPRENANT LADITE UNITE DE TERMINAISON La méthode est utilisée dans un réseau de télécommunications où une station centrale (CS) est reliée à un certain nombre de résidences (R1, R2, R3). Une des résidences (R3) comprend une unité de terminaison (TU) qui est reliée à la station centrale (CS) par l'intermédiaire d'un premier port (P1). La résidence (R3) comprend également des terminaux d'abonné, p. ex. un ordinateur personnel (PC), un téléphone (TEL), un téléviseur (TV) et un coffret d'abonné qui sont reliés à l'unité de terminaison (TU) par l'intermédiaire d'un deuxième port (P2). La méthode comprend l'amplification d'un signal d'amont (US) appliqué au deuxième port (P2) avec une valeur de gain d'amont (UG) au moyen d'un amplificateur de signal d'amont (U-AMP3) qui fait partie de l'unité de terminaison (TU). Un signal d'amont amplifié (AUS) est ainsi produit et transmis au premier port (P1). Le gain d'amont (UG) compense l'affaiblissement de la puissance du signal sur la ligne de transmission interne (UA-Li) entre l'unité de terminaison (TU) et un des terminaux d'abonné, qui constitue en fait l'affaiblissement du réseau interne. Cela permet de réduire la diaphonie dans la région de la ligne de transmission interne au niveau des terminaux d'abonné en réduisant les différences entre les niveaux de puissance du signal. (figure)

Patent CA-2226512-A1 (CA)
Inventor: CHOU WEI FAN JOHN
IPC: H05B37/02
Filed: 1997-04-30
Abstract: A lighting control circuit that controls the lighting of particular lamps in response to the toggling of the power switch. The circuit a) connects only with the high (output) side of a lighting system's ballast, b) is completely contained on the high side, and c) with regard to toggling, is dependent upon only a single time period. The circuit can be used with any ballast which makes use of an output tranformer and no change need be made to the original ballast circuitry. Users will find operation of the circuit to be straightforward. A triac driven by a flip-flop via a driver transistor is used to control the high frequency AC power that is used to drive the lamps. A Schmitt trigger sharpens the signal generated by the ballast output transformer in response to the toggling of the light switch which is employed to change the output state of the flip-flop. Operationally, all the lamps driven by the ballast are lit when the power switch is initially turned on. Toggling the power switch once while all of the lamps are lit causes only a predetermined number of the lamps to remain lit.     Toggling the power switch while only a portion of the lamps are lit causes all of the lamps to light again. Leaving the power switch off causes all of the lamps to be turned off. The toggling may be performed quickly or leisurely, so long as the entire toggle cycle is completed within a predetermined amount of time.

Title: Method for isolating xylanase gene sequences from soil dna, compositions useful in such method and compositions obtained thereby
Inventor: SEOW KAH TONG
IPC: C12Q1/6806
Filed: 1996-09-20
Abstract: Xylanase DNA is recovered from soil by PCR amplification using degenerate primers. Because of the complexity of the soil samples, it is likely that the recovered product will include more than one species of polynucleotide. These recovered copies may be cloned into a host organism to produce additional copies of each individual species prior to characterization by sequencing.  Recovered DNA which is found to vary from known xylanases can be used in several ways to facilitate production of novel xylanases for industrial application. First, the recovered DNA, or probes corresponding to portions thereof, can be used as a probe to screen DNA libraries and recover intact xylanase genes including the unique regions of the recovered DNA. Second, the recovered DNA or polynucleotides corresponding to portions thereof, can be inserted into a known xylanase gene to produce a recombinant xylanase gene with the sequence variations of the recovered DNA.

IPC: G06F19/00
Filed: 1997-02-07
Abstract: Methods are provided for developing medical diagnostic tests using decision-support systems, such as neural networks. Patient data or information, typically patient history or clinical data, are analyzed by the decision-support systems to identify important or relevant variables and decision-support systems are trained on the patient data. Patient data are augmented by biochemical test data, or results, where available, to refine performance. The resulting decision-support systems are employed to evaluate specific observation values and test results, to guide the development of biochemical or other diagnostic tests, to assess a course of treatment, to identify new diagnostic tests and disease markers, to identify useful therapies, and to provide the decision-support functionality for the test. Methods for identification of important input variables for medical diagnostic tests for use in training the decision-support systems to guide the development of the tests, for improving the sensitivity and specificity of such tests, and for selecting diagnostic tests that improve overall diagnosis of, or potential for, a disease state and that permit the effectiveness of a selected therapeutic protocol to be assessed are provided. The methods for identification can be applied in any field in which statistics are used to determine outcomes. A method for evaluating the effectiveness of any given diagnostic test is also provided.

Inventor: SIEGENTHALER MAX
IPC: E21B44/06
Filed: 1998-09-23
Abstract: The rock drill (9) comprises a reversible rotary motor (10) and a percussion unit  (11)  with a percussion valve  (17).   Rotary unit and Percussion unit  (11)  are operated via separate valves (39,  46)  in a control unit  (34).   The percussion frequency of the percussion unit (11) is coupled to the rotation rate of the rotary motor (10) in such a way, that the percussion unit  (11) stops  automatically  when  the  rotary motor  (10)  comes  to  a standstill.  The coupling is achieved by employing fluid driven means without mechanical clutch between rotary motor  (10)  and percussion valve  (17).   When disassembling the drill  rods  a jammed thread can be shaken loose with the percussion unit (11) be manually bypassing the fluid coupling.   The same is also possible in case the drill rods becomes jammed in the drill bore.  With the described embodiment a simple, space-saving and cost-effective construction is achieved which is versatile in application.

Title: Continuously cleaned pressureless water heater with immersed copper fluid coil
Inventor: HARRIS HOWARD
IPC: F24H1/20
Filed: 1998-10-02
Abstract: A pressureless electric water heater for domestic use has a cylindrical double-walled tank for holding a quantity of a heat transfer liquid such as water. Cold water enters a copper coil immersed in the heat transfer liquid. The heat transfer liquid is heated by an electric heating element which extends down from a hinged tank top and exits the coil as water heated by an electric heating element. The hinged top allows easy access to the interior of the tank and to the heating element, further easing access and replacement thereof. Sedimentation in the tank is minimized because the tank water is rarely replaced. Sedimentation is the coil reduced because pressurized water flows through the coil when hot water is required and continuously cleanses the pipe.

Patent CA-2252329-A1 (CA)
Title: Precision liquid injection system
Inventor: BRASS JACK
IPC: F04B9/14
Filed: 1998-11-03
Abstract: There is provided an injector for use in injecting a liquid into a pressurized system such as an air conditioning system. The injector has a tubular spindle having a longitudinal axis, an open end, and an opposing partially closed end. The spindle open end and spindle closed end define a cylindrical bore along the longitudinal axis of the spindle. A cylindrical piston within the spindle bore is axially aligned with the longitudinal axis of the spindle. There are sealing means such as O-ring seals between the spindle and the piston. The spindle, piston and sealing means define a chamber between the piston and the spindle closed end within the bore. A  tubular driver sleeve has a longitudinal axis, an open end and an opposing closed end. The driver sleeve has threads around an interior surface of the sleeve and the spindle has compatible threads around an exterior surface of the spindle such that rotation of the driver sleeve in one direction screws the driver sleeve towards the spindle closed end. This causes the piston to move towards the spindle closed end and exert pressure on the chamber.
